Pressure Pain Threshold Values Obtained Through Algometers

Pain intensity can provide relevant medical information; nowadays, pain measuring is still subjective; therefore, there are efforts to develop devices to measure the intensity of painful stimuli objectively. A review of the scientific literature on pressure pain obtained through algometers is carried out in this work. This literature review aims to present a database of pain pressure thresholds (PPT) related to different body parts so that future research on PPT, using an algometer, could compare their results against this research. The results of these PPT values are presented and grouped according to the body regions where previous researchers recorded their results to where they applied the pressure- trapezius muscles, back muscles, upper extremities, leg muscles, foot area, and muscles of the head. These values can be considered a reference to evaluate new algometers' accuracy and reliability. Finally, the algometers operational parameters range are defined according to all the studied algometers.
